| Abstract: | The effects of application N, P and K fertilizers on the double-low rapeseed cultivar Zhongshuang No.7 were investigated under red paddy soil of two-crop paddy and rapeseed cropping system in Jiangxi province. Approaches of applying N 240kg/hm 2, P 2O 5 60kg/hm 2, K 2O 90kg/hm 2 and boron fertilizer 15kg/hm 2 were recommended for increasing content of plant nitrogen and phosphorus during the growth stages. In this experiment the biomass was increased and yield of Zhongshuang No.7 was 2 437.5kg/hm 2, which significantly higher than NK, NP and N approaches. |
